Rock solid EQ mount

By James A. Edwards on October, 16th 2009

Having used various Fork type mounts, my first experience was with the G-11 Gemini...Well made, very good quality mechcanically and the go-to and tracking are exceptional...The hand controller takes a little getting used to but this mount can easily be sync to your personal lap top and works extremly good with either application...My only wish was the additional knobs etc...which I feel should be included as they round this mount out nicely!

Excellent quality and value

By Joel Guthals on October, 16th 2009

After using the G-11/Gemini for more than one year, I continue to be impressed with its high quality engineering and manufacture. Although the Gemini control system takes a little practice, after a few sessions it becomes easy to use, including the five button hand controller about which some complain. The mount is very accurate and stable. The Gemini has many unique functions such as allowing automatically parking of the mount at he end of a viewing session and providing automatic object searching. I am using the G-11 for my Tak FS-152 and C-14. It handles both scopes easily.

Good, but could be Great.

By Paul Atkinson on October, 16th 2009

This mount is capable of holding more than stated for visual use only, which is how I use it. Have C14 and accessories and have had in decent breeze without terrible problems. Hand controller stinks. 4 buttons for everything means pushing them over and over to preform all functions and selecting objects. Other low mark is that you must do several additional aligns to get accurate on both sides of Meridian. GOTO very good after that. Overall good but could be great with a few changes.
